Warm olive oil in a lg, thick-bottomed pot over med-high heat. Stir in the salt & potatoes. Cover & cook until they are slightly tender & starting to brown a bit, about 5 mins - it's okay to uncover to stir a couple times. Stir in garlic & onion & cook for 1-2 more mins. Add stock & beans & bring the pot to a simmer. Stir in cabbage & cook for a couple more minutes, until the cabbage softens up a bit. Now adjust the seasoning - getting the seasoning right is important or your soup will taste flat & uninteresting. Taste & add more salt, if needed; the amount of salt you will need to add will depend on how salty your stock is (varying widely between brands, homemade, etc)...Serve drizzled with a bit of olive oil & a generous dusting of cheese. Serves 4.
